Quick Setup Guide

QUICK SETUP GUIDE

In case you simply cannot wait to experience the performance of your 
new NAD M28 Seven Channel Power Amplifier, the following QUICK SETUP 
GUIDE is recommended to help you get started.
 
Ensure that the M28 is unplugged before making any connections. It is 
also advisable to power-down or unplug all associated components while 
making or breaking any signal or AC power connections.

Set the external source's volume control to minimum level. External 
source can be a preamplifier, processor, amplifier or any applicable 
device.

Set SELECT switch to BALANCED or SINGLE-ENDED. Connect the analog 
audio output of your external source to the M28 rear panel’s BALANCED 
or SINGLE-ENDED analog audio input. Depending upon the source’s 
configuration, analog audio input connection can be made up to seven 
channels either via BALANCED or SINGLE-ENDED input ports. 

Connect your speakers to the SPEAKER terminals of M28.  Note 
suggested speaker connections as reflected in the rear panel channel 
allocations.   

Plug-in to a mains power source the M28’s supplied mains power cord. 
Connect corresponding end of the mains power cord to the AC mains 
input of M28 and the plug connected to a mains power source.

Plug-in also to a mains power source the external source’s mains power 
cord.  Power up the external source ahead of the M28. 

Set to ON the rear panel POWER switch of M28. The M28 goes to 
standby mode as shown by the amber status condition of the Power 
indicator. 

Press 

o

 (Standby) button for the M28 to be switched ON from standby 

mode. The Power indicator will turn from amber to bright/white color. 
The M28 is ready for operation.

Adjust the external source’s volume control according to desired 
listening level. 

SAVE THE PACKAGING

Please save the box and all of the packaging in which your M28 arrived. 
Should you move or otherwise need to transport your M28, this is by far 
the safest container in which to do so. We’ve seen too many otherwise 
perfect components damaged in transit for lack of a proper shipping 
carton, so please: Save that box!

NOTES ON INSTALLATION

• 

Your NAD M28 should be placed on a firm, level surface.

Avoid placing the unit in direct sunlight or near sources of heat and 
damp. 

• 

Allow adequate ventilation. 

• 

Do not place the unit on a soft surface like a carpet.  

• 

Avoid placing the M28 inside a closed cabinet that is not well ventilated 
as this may compromise the M28’s performance and reliability.  

• 

Ensure that the M28 is unplugged before making any connections.  

• 

For best performance, use quality speaker leads of 16 gauge (1.5mm

2

thickness or more.  

• 

If the unit is not going to be used for some time, disconnect the plug 
from the mains power source.

BARE WIRES AND PIN CONNECTORS

WARNING:

 The terminals marked with this symbol 

are hazardous live.  External wiring connected to these 
terminals requires installation by an instructed person or 
the use of ready-made leads or cords.

Bare wires and pin sockets should be inserted into the hole in the shaft 
of the terminal. Unscrew the speaker terminal’s plastic bushing until the 
hole in the screw shaft is revealed. Insert the pin or bare cable end into 
the hole and secure the cable by tightening down the terminal’s bushing. 
Ensure bare wire from the speaker cables does not touch the back panel or 
another socket. Ensure that there is only 1/2” (1cm) of bare cable or pin and 
no loose strands of speakers wire.

The supplied magnetic feet can be easily installed by aligning and attaching 
them to their corresponding foot shoe.  Refer to illustration below.
